Thus, the definition of noise elution is open to debate, and there is no clear border as to which sounds may constitute noise pollution. In the narrowest sense, sounds are considered noise pollution if they adversely affect wildlife, human activity, or are capable of damaging physical structures on a regular, repeating basis. In the broadest sense of the term, a sound may be considered noise pollution if it disturbs any natural process or causes human harm, even if the sound does not occur on a regular basis. [pick] The prevailing source of artificial noise pollution is from transportation.
In rural areas, train and airplane noise can sister wildlife habits, thereby affecting the manner in which animals in areas around train tracks and airports hunt and mate. In urban areas, automobile, motorcycle, and even entertainment noise can cause sleep disruption in humans and animals, hearing loss, heart disease (as a result of stress), and in severe cases even mental instability. A notable exception to the rule is the electric, or hybrid-electric, automobile. Hybrid vehicles are so quite, in fact, that legislation is pending to actually make them louder.
This is in response to numerous injuries in which pedestrians, unaware of a hybrid vehicle’s residence, have been struck by such vehicles in parking lots and pedestrian crosswalks. As far as noise pollution is concerned, the monitoring is done mainly during festivals such as Dependable. A few Specs and BPCS have initiated regular noise monitoring since 2008-09. As per available data, the laid down noise norms for respective zones (Industrial, Commercial, Residential or Silence) are exceeded at many locations.
However, a definite trend cannot be ascertained for major cities, including Hydrated, since data is available only for a limited period. The practice of exploding sound minting firecrackers on religious occasions & weddings, playing of bands during processions, blowing of horns, operation of generator sets, movement of traffic (highways, railways and airways), use of public address systems, construction activities and operation of generator sets increase the ambient noise levels in urban areas. What causes Noise pollution? 1.
Road Traffic Noise:- In the city, the main sources of traffic noise are the motors and exhaust system of autos , smaller trucks, buses, and motorcycles. This type of noise can be augmented by narrow streets and tall buildings, which produce a canyon in which traffic noise reverberates. [pick] 2. Air Craft Noise: – Now-a-days , the problem of low flying military aircraft has added a new dimension to community annoyance, as the nation seeks to improve its nap-of the- earth aircraft operations over national parks, wilderness areas , and other areas previously unaffected by aircraft noise has claimed national attention over recent years. . Noise from railroads: – The noise from locomotive engines, horns and whistles, and switching and shunting operation in rail yards can impact neighboring communities and railroad workers. For example, rail car retards can produce a high frequency, high level screech that can reach peak levels of 120 db at a distance of 1 00 feet, which translates to levels as high as 1 38, or 140 db at the railroad worker’s ear. 4. Construction Noise: – The noise from the construction of highways, city streets, and buildings is a major contributor to the urban scene.
Construction noise sources include pneumatic hammers, air compressors, bulldozers, loaders, dump trucks (and their back-up signals), and pavement breakers. 5. Noise from Industry: – Although industrial noise is one of the less prevalent immunity noise problems, neighbors of noisy manufacturing plants can be disturbed by sources such as fans, motors, and compressors mounted on the outside of buildings Interior noise can also be transmitted to the community through open windows and doors, and even through building walls.
These interior noise sources have significant impacts on industrial workers, among whom noise- induced hearing loss is unfortunately common. 6. Noise in building: – Apartment dwellers are often annoyed by noise in their homes, especially when the building is not well designed and constructed. In this ease, internal building noise from plumbing, boilers, generators, air conditioners, and fans, can be audible and annoying. Improperly insulated walls and ceilings can reveal the sound of-amplified music, voices, footfalls and noisy activities from neighboring units.
External noise from emergency vehicles, traffic, refuse collection, and other city noises can be a problem for urban residents, especially when windows are open or insufficiently glazed. [pick] 7. Noise from Consumer products and crackers: – Certain household equipment, such as vacuum cleaners and some kitchen appliances have been ND continue to be noisemakers, although their contribution to the daily noise dose is usually not very large.
Effects of Noise pollution It decreases the efficiency of a man: – Regarding the impact of noise on human efficiency there are number of experiments which print out the fact that human efficiency increases with noise reduction. A study in India has suggested that reducing industrial booths could improve the quality Of their work. Thus human efficiency is related with noise. Lack of concentration: – For better quality of work there should be concentration, Noise causes lack of concentration. In big cities, mostly all the offices are on main road.
The noise of traffic or the loud speakers of different types of horns divert the attention of the people working in offices. Fatigue: – Because of Noise Pollution, people cannot concentrate on their work. Thus they have to give their more time for completing the work and they feel tiring. Abortion is caused: – There should be cool and calm atmosphere during the pregnancy. Unpleasant sounds make a lady of irritate nature. Sudden Noise causes abortion in females. It causes Blood Pressure: – Noise Pollution causes certain diseases in human. It attacks on the person’s peace of mind.
Measures to control Noise pollution. No one on earth can escape the sounds of noise- an unwanted, disturbing sound that causes a nuisance in the eye of the beholder. Noise is a disturbance to the human environment that is escalating at such a high rate that it will become a major threat to the quality of human lives. In the past thirty years, noises in all areas, especially in urban areas, have been increasing rapidly. There are numerous effects on the human environment due to the increase in noise pollution. In the following paper, the cause and effects of noise pollution will be presented in some detail.
Slowly, insensibly, we seem to accept noise and the physiological and psychological deterioration that accompanies it as an inevitable part of our lives. Although we attempt to set standards for some of the most major sources of noise, we often are unable to monitor them. Major sources of noise can be airplanes at takeoff and landing, and a truck just off the assembly line, yet we seem accept and enjoy countless other sounds, from hard rock music to loud Harley Davidson motor cycles. [pick]Some towns and cities actually have laws and emits as to the noise pollution that Its citizens can make.
Other places, like golf courses or nature reserves, are also considered to be “quieter” places with less noise pollution. There are some things that all people can do to help lower their own levels of noise pollution that they – and hopefully others around them – produce. Rake leaves by hand; don’t use a noisy leaf blower. Trim bushes or shrubs by hand; don’t use a noisy bush trimmer. Sound proof rooms that might have music conducted in them, like a room with a piano or if someone in the house plays drums or guitar or whatever. This can e done simply with curtains, window inserts, carpeting, and closing windows and doors.
Don’t blast music on the radio or computer or speakers. Be considerate of your own ears and those of other around you. Don’t slam doors / car doors, close them easily and with only as much force as needed. Turn off the TV or radio when you aren’t actually fully listening to it. Train your dog not to bark so much. Don’t yell. Have civil conversations. Call someone or go find them instead of yelling across the street for them, for example. Plant trees and bushes around you house. They help keep the air clean, absorb mound, give privacy, and add nice design and looks to a house.
Do noisy things (dishes, hammering, etc. ) over or on a rubber mat to reduce noise. Put carpets, rugs, mats, throw rugs, etc. In your house / mats outside. Put fabric window coverings instead of plastic or wooden shades / blinds. Don’t rev up a motorcycle or car unless it is actually needed for the drive. Don’t beep your car horn “just because”; make sure it is a legitimate reason. Conclusion [pick]We have made the law relating to noise pollution but there is need to creating general awareness towards the hazardous effects of noise pollution.
Particularly, in our country the people generally lack consciousness of the ill effects which noise pollution creates ad how the society including them themselves stand to beneficiary preventing generation and emission of noise pollution. The target area should be educational institutions and more particularly school. The young children of impressionable age should be motivated to desist from playing with firecrackers, use of high sound producing equipments and instruments on festivals, religious and social functions, family get-together and celebrations etc. Which cause noise pollution.
Suitable chapters can be added into textbooks, which teach civic sense to the children and teach them how to be good and responsible citizen which would include learning by heart of various fundamental duties and that would obliviously include learning not to create noise pollution and to prevent if generated by others. Holding of special talks and lectures can be organized in the schools to highlight the menace of noise pollution and the role of the children in preventing it. For these purpose the state must pay its role by the support and cooperation of non-government organizations (NAGS) can also be enlisted.
